YROTATE CAMERA

This command will move the camera in the direction it is facing.

The step value specifies how far to move the camera and should be a real number.

• Syntax • YROTATE CAMERA YAngle• YROTATE CAMERA Camera Number, YAngle

• Example• YROTATE CAMERA 0

XROTATE CAMERA

This command will rotate the camera around its X axis.

The angle value should be a real number.

• Syntax • XROTATE CAMERA XAngle• XROTATE CAMERA Camera Number, XAngle

• Example• XROTATE CAMERA 0

CAMERA ANGLE Y This command will return the real value Y angle of the camera.

• Syntax • Return Float=CAMERA ANGLE Y()• Return Float=CAMERA ANGLE Y(Camera Number)

• Example• CAMERA ANGLE Y(0)-3

WRAPVALUE This command will return a value that does not exceed the range of 0 to 360.

Where a value is specified that exceeds this range,

the command will wrap the value around to bring it back within the range.

• Syntax • Return Float=WRAPVALUE(Angle Value)

• Example• WRAPVALUE(CAMERA ANGLE Y(0)-3)

MOUSEMOVEX

This command will get the current integer X movement value of the mouse pointer.

Instead of the actual mouse position, this command returns the difference between

the current mouse X position and the last mouse X position.

• Syntax • Return Integer=MOUSEMOVEX()

• Example• MOUSEMOVEX()*0.2

http://www.prasansoft.com

MOUSEMOVEY This command will get the current integer Y

movement value of the mouse pointer. Instead of the actual mouse position, this command returns the difference between the current mouse Y position and the last mouse Y position.

• Syntax • Return Integer=MOUSEMOVEY()

• Example

• MOUSEMOVEY()*0.2
